The Serverless Model

IaaS, PaaS, SaaS are not the only models that can be run in the Cloud

The Serverless Model

• There are still servers...

• You just don't ever have to deal with them

• Even less access to the servers than PaaS

PaaS Notes:

• Even with PaaS, you have to choose an App Service Plan

• Within PaaS, scaling is your responsibilit

Serverless means not worrying about choosing the right plan Serverless means bit worrying about scaling Serverless means you might pay $0 if you don't use the service (since you are paying for execution)
